On Cloudboom Max review: what runners say

Fit

True to size for most runners; some report the model runs short compared to other On shoes, with risk of toe box pressure. Narrow or low-volume feet may find the upper too wide.

Feel

Cushioning is present but muted: the fiberglass plate stiffens the system without delivering energy return. Ride feels locked down, lacking effective rocker and toe spring.

Durability

Generous rubber coverage at forefoot and heel; sources indicate good wear resistance, with no specific mileage figure stated.

Best for

Marathoners running 4:00–5:00 pace, heavier runners, or those seeking stability over long distances. Not suited for sustained fast paces or runners wanting responsiveness.

Weak points

High weight (298–315 g depending on size) is disproportionate for a race shoe. Excessive stiffness causes foot and calf fatigue after 10–12 km; reports of toe area hot spots and defective internal stitching.
